Cant use Lightbox clones

Permalink
Seems that there is a problem with using lightbox clones like PrettyPhoto or CeeBox with C5?

Im doing exactly as it says in the setup instructions, including import of jQuery, which I use without problem on my site.

This site is local and I begin to link in the .js-file with this:

<script type="text/javascript" src="http://192.168.1.2:8080/concrete5/concrete/js/jquery.prettyPhoto.js"></script>

This is AFTER the import of jQuery 1.3.2 lib. Note that I access the js-code when pasting it into the browser.
Then in document.ready() I try to init it with these lines:
$(document).ready(function(){
          $("a[rel^='prettyPhoto']").prettyPhoto();
});
Please ignore the php-tags

Doesnt matter which clone I try to implement and use, all I get is an Error in Firebugg saying:
$("a[rel^='prettyPhoto']").prettyPhoto is not a function
